Släkthistoria för Piatt
Piatt Vad efternamn betyder
Altered form of French and Walloon Piat: from the personal name Piat from the Latin name Piatus ‘expiated’ (from the past participle of the verb pio ‘to appease; to expiate’). The name was borne by Saint Piatus of Tournai (in Wallonia Belgium) who was martyred under the Roman Emperor Maximian c. 286 AD . Altered ending of the surname reflects the Canadian and American French practice of sounding the final -t. Compare Pyatt. English (Lancashire and Cheshire): variant of Pyatt.
